The thing that surprised me was seeing Bigach at DE and Gaglione at DT.
My impression there is that looking to the future, we're going to need some good guys to be able to start for us at DE in 2012. Due to graduation ... we're going to be losing 3 guys at DE from the depth chart ... and our overall depth behind those guys is nil.
Thus, if I were to guess ... the coaches figure that Alvis and Bigach are our best bets to be solid starters at DE for the '12 season. Then, from there, we need to be able to have guys who are ready to step up at DT. And, to that end, we're kinda better off at DT concerning upside and depth. Davis, Cooper, and Trinca-Pasat will combine to keep the DT spot well stocked .... and Jaleel Johnson could definitely work his way into the picture as soon as '12 too (although I hope he redshirts).
BTW ... if you watch the week 3 video finale of fall-camp ... it looks like Spears has been working at DE. I like the move ... and I hope that he really embraces it too.
